• establishing a constant connection session with each of the plurality of second apparatuses by a constant connection session establishment means of the server apparatus;
• transmitting a second request to directly transfer data between the plurality of second apparatuses to the second apparatus as the data transfer destination through the constant connection session by a second request transmission means of the server apparatus in response to the first request received from the first apparatus, wherein the second request includes login identification information of the second apparatus as the data transfer source required for the second apparatus as the data transfer source to log into the server apparatus;
• determining, based on information from the second apparatus as the data transfer destination relating to an access route between the second apparatus as the data transfer source and the second apparatus as the data transfer destination, the information relating to the access route being based on a determination by the second apparatus as the data transfer destination whether the login identification information of the second request coincides with login identification information of the second apparatus as the data transfer source stored at the second apparatus as the data transfer destination as login identification of an apparatus among the second apparatuses connected to the second apparatus as the data transfer destination via a same local access network, (i) the access route between the second apparatus as the data transfer source and the second apparatus as the data transfer destination is via the same local access network on which the second apparatus as the data transfer source and the second apparatus as the data transfer destination are connected as opposed to (ii) the access route between the second apparatus as the data transfer source and the second apparatus as the data transfer destination is via the Internet, and
• transferring data between the plurality of second apparatuses by a data transfer means of the plurality of second apparatuses in response to the second request from the server apparatus.

A non-transitory storage medium recorded with a computer-readable program executable by a computer, wherein the program comprises:

• associating a first apparatus with a plurality of second apparatuses as the control targets thereof and registering the first apparatus and the plurality of second apparatuses associated,
• establishing a constant connection session with each of the plurality of second apparatuses,
• receiving from the first apparatus a first request to transfer data between the plurality of second apparatuses, wherein the first request includes information to specify one of the plurality of second apparatuses as a data transfer source and information to specify one of the plurality of second apparatuses as a data transfer destination,
• transmitting a second request to directly transfer data between the plurality of second apparatuses to the second apparatus as the data transfer destination through the constant connection session in response to the received first request, wherein the second request includes login identification information of the second apparatus as the data transfer source required for the second apparatus as the data transfer source to log into a server, and
• determining, based on information from the second apparatus as the data transfer destination relating to an access route between the second apparatus as the data transfer source and the second apparatus as the data transfer destination, the information relating to the access route being based on a determination by the second apparatus as the data transfer destination whether the login identification information of the second request coincides with login identification information of the second apparatus as the data transfer source stored at the second apparatus as the data transfer destination as login identification of an apparatus among the second apparatuses connected to the second apparatus as the data transfer destination via a same local access network, (i) the access route between the second apparatus as the data transfer source and the second apparatus as the data transfer destination is via the same local access network on which the second apparatus as the data transfer source and the second apparatus as the data transfer destination are connected as opposed to (ii) the access route between the second apparatus as the data transfer source and the second apparatus as the data transfer destination is via the Internet.
